Title:
TITANIUM PHOSPHINIMIDE AND TITANIUM IMINOIMIDAZOLIDIDE CATALYST SYSTEMS WITH ACTIVATOR-SUPPORTS
Document Type and Number:
WIPO Patent Application WO/2016/057270
Kind Code:
A3
Abstract:
Catalyst compositions containing activator-supports and half-metallocene titanium phosphinimide complexes or half-metallocene titanium iminoimidazolidide complexes are disclosed. These catalyst compositions can be used to produce olefin polymers having relatively broad molecular weight distributions and low levels of long chain branching.
